.MEANS FOR GRIPPING AND COUPLING- WIBE ROPES, RODS, &c.

Specification of Letters Patent.

Patented Dec. 24, 1907.

ipplication filed March 25 1904-. Serial No. 200.06%. I

alongside and parallel with each other, and

its object is to dispense with the slow and unsatisfactory method of! effecting the connection by wire lashings as heretofore, as well as to prevent the wastie of the rope and wire in forming such connections.

According to the invention I employ a metal sleeve, yoke, oi; clamp slightly tapered on its exterior, and wide enough" to allow two or more ropes to pass through it. Such sleeve I split (or slit) in. part longitudinally and upon its interior faces I form channels or grooves corresponding in diameter to the size of rope or ropes to be gripped. The

tapered exterior of the clamp is screwthreaded to receive a nut, so that when tightened up the nut serves o contract the sleeve and cause it to gripthu ropes.

In order that my invention shall be clearly understoml I have hereunto appended a sheet of drawings, wherein Figure 1 illustrates an. exterior elevation of the complete coupling and such View also shows one of its chief uses i. e, a suostitute for lashings in. prmlu ing aloop at the end of a wire rope largely used in telegraph and like work. Fig. 2 illustrates a longitudinal section with parts of ti c ro )e removed in order to show the interior roug ening of the grooves. Figs. 3, 4 and 5 illustrate the two main parts of the coupling separately, Fig. 3 being partly in section and Fig. 5 being an end view of Fig. 4. Fig. 6 illustrates an end view of another -form of the improved coupling.

Referring to Figs. 1 to 5, (a) is the afore" said sleeve or clamp part with screwdhreaded and tapered or conical exterior. In such part are the borings (5:), (b). Passing completely through the sleeve, except for a small portion at the-wider end, and through the plane of the borings is a saw cut or slit (0) producing segmental jaws (1), (2), see Fig. 5. (d) is the tightening nut, which is, by preference,v slightly conical upon its interior in keeping with the taper of. the sleeve ((1), see 7 Figs. 2 and 3. Upon the larger end the sleeve is a flange (c) with holes for a tommyor of hexagonal shape for a spanner.

When assembled and in use the several parts occupy the positions shown in Fig. i,

the wire rope by being turned back on itself forming the loop, and the couplin by firmly gripping the two parts offering a hrm resistance to theloop coming loose.

Obviously, instead of gripping two parts of the same rope the coupling may griptwo separate ropes, or a rope and a rod, themain purpose of my invention being to hold by the same clamp two or more objects, or two or more parts of an object lying side by side.

For coupling three or more ropes I form the coupling with borings to suit, and to provide the necessary grip with each I slit the sleeve through each boring.

In Fig. 6 I show how the block'is formed for clamping two looped ropes four separate.

ropes, or one loo ed rope and two separate ropes, the extra slit (0) extending only to the flange e).

To increase the grip I may groove, serrate or rille the interior faces of the boringsas shown in Fig. 2, the grooving being either inv the form of single screw threads or to the pat tern of the rope.

W'h at I claim is For gripping two lashings or the like side by side and by one adjustment, the combination of a conical metal block with its exterior of conical formation and screw threaded, and also having a nut-like boss at one end, and said block formed with borings extending from end to end of the block and also grooved internally andsaid block also slit longitudiually in part and a nut with tapered and screwthreaded interior for contracting the block simultaneously upon the two lashings passing through theborings, set forth.

In witness whereof I have hereunto set my hand in the presence-of two witnesses.

JAMES Moss.
